Another option would be the BC Math package which will let you compute
arbitrarily large numbers, albeit a bit slower.

Just how big do the numbers get?...

RE: [PHP] Re: Help needed with hexdec();

[frank]

Thank you for your answer Richard, unfortunately the port from perl to
PHP didn't work out the way I wanted it to - probably mainly because of
the lack of perl knowledge here.

And yes you are right, the numbers I use are a lot bigger than
2147483647.

If anyone has an idea on how to treat the numbers or hex number for that
matter please don't hesitate. 

Anyway, I'm dropping the project for now.

Thanks again.

I'm betting your numbers are bigger than that.

I wrote a less-limited hex2dec function years ago, and threw it up on
Sklar,
or, uhhh, the *other* PHP code repository.  There were really only two,
back
then... :-)
